Vince McMahon once challenged Dana White to a pro wrestling match for Wrestlemania

MMA and professional wrestling share plenty of fans. After all, it was the WWE's lead-in to "The Ultimate Fighter" years ago that helped make the show a success on Spike. Brock Lesnar was a huge star in pro wrestling before becoming the UFC heavyweight champion. After losing his belt and retiring from MMA, he went back to WWE. But could even the most ardent fans of both sports couldn't expect to see the executives of the UFC and WWE take each other on, right?

Well, according to UFC president Dana White, he was once challenged to a match by WWE chairman Vince McMahon.

"Vince is too old, which he won't think he is and he'll go crazy," White said during an interview with Canada's RDS. "He wanted to do that one time. Vince wanted to fight me. Swear to God, he called me up and said, `Let's do it. We can either do it in the UFC or let's do it at WrestleMania.' And I said, `You are crazy. I always said I respect Vince and I'll say it again. I respect Vince very much, but Vince is too old to be fighting."

MMA Fighting says this happened in 2010, when McMahon was 65 and White was 41. McMahon was ready to make the headline event of Wrestlemania 27 a staged or real match between him and White. But White didn't ever entertain the idea.

"I laughed and said, 'You're crazy, you're out of your mind,' White said on Fuel TV. "In the interview (the night before), I said Vince was too old. We're both too old. I'm too old, too, just for the record."

But crazy ideas helped McMahon become the gajillionaire he is today. Would you spend the money on a pay-per-view to watch men who are "too old" in a pro wrestling match? Speak up in the comments, Facebook or on Twitter.
